TYPE LOCATION: Catron County, New Mexico; near Zuni Salt Lake in the SW1/4, NW1/4, sec. 30, T. 3 N., R. 18 W.
RANGE IN CHARACTERISTICS:
Soil moisture: Ustic aridic moisture regime
Depth of soil: 40 to 60 inches or more
Reaction: moderately to strongly alkaline
Clay content: less than 18 percent clay
Carbonates: less than 15 percent calcium carbonate
A horizon
Hue: 10YR
Value: 4 through 7 dry, 2 through 4 moist
Chroma: 2 or 3
Texture: loamy sand or sandy loam.
C Horizon
Hue: 10YR
Value: 4 through 7 dry, 2 through 4 moist
Chroma: 2 or 3
Texture: highly stratified loamy sand or sandy loam
Cementation: In some pedons, the C horizon has several thin strata that are weakly to strongly cemented with silica and calcium carbonate.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: The Hubbell soils developed on nearly level to moderately sloping landscapes covered with volcanic sediments adjacent to cinder cones and craters.
The mean annual air temperature ranges from 47 to 54 degrees F. The average annual precipitation is about 10 to 14 inches. The frost-free season varies from 140 to 180 days. Elevation is 6,200 to 6,800 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Celacy (P), Ceniza (P), Jacee (P), and Vermejo soils. Celacy and Jacee soils have argillic horizons. Ceniza soils have greater than 35 percent coarse cinder fragments in the control section. Tejana soils are in a fine-loamy family. The Vermejo soils are in a fine family.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately rapid permeability.
USE AND VEGETATION: Most of the soils are used for grazing. The sparse native vegetation is mainly fourwing saltbush, alkali sacaton, blue grama, alkali sacaton, globemallow, snakeweed, and scattered junipers.
DISTRIBUTION AND EXTENT: Westcentral New Mexico. Series is of small extent, about 7,000 acres. MLRA 35.

SERIES ESTABLISHED: Catron County, New Mexico, 1982.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - The zone from 0 to 4 inches (A horizons)
Classified according to Keys to Soil Taxonomy Tenth Edition, 2006
Classification changed from Typic Ustorthents to Ustic Torriorthents in 2006. This soil is in a 10-14" precipitation zone that is clearly in an Ustic aridic moisture regime.
The name came from a large ranch in the area.
